So a couple of years ago I was reading an academic article somewhere about the Moving Spotlight theory of time and it brought up the concept of "supertime"
Now let me make it clear that
1) I find Moving Spotlight to be pointlessly complex and somewhat nonsensical, but also
2) I don't know enough about the world yet and I obviously fully respect whoever wrote about it
I'm getting sidetracked; I just made this silly little tumblr dot com post to say that I although I find the entire concept of a "supertime" needlessly overcomplicated in Moving Spotlight theory, I keep accidentally returning to it when it comes to time travel.
If you move faster, then you move faster through time relative to your (slower) surroundings. There's obviously (presumably) no absolute way to quantify your rate of passage through time in terms of "seconds per supersecond"; it's going to just be a ratio to compared to your surroundings. If anything, a supersecond would be an arbitrarily chosen reference frame with which to compare.
But could there such a thing as a sort of "temporal velocity" to measure how quickly you go through time compared to your surroundings and consequently other attributes like temporal forces, kinetic energy, etc? Under special relativity this is presumably all negated by rate of passage being inherently tied to velocity, and I haven't formally studied general relativity yet so I can't say anything about that. Just random thoughts about time.
